Beli Manastir Wastewater Treatment Plant - Secondary Treatment in Osijek-Baranja, Croatia

The Beli Manastir wastewater treatment plant is located in the town of Beli Manastir, in the Osijek-Baranja County of eastern Croatia. The plant serves the local population as part of the municipal wastewater infrastructure for this inland community. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. With a designed capacity of 8,000 m³/day, the facility is sized to handle the wastewater from the town and surrounding area. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube River flows into the Black Sea, making this plant part of a large international watershed. Proper treatment helps protect downstream aquatic ecosystems and water quality in the Danube Delta.

The plant discharges into the Danube River basin, which flows through several countries before reaching the Black Sea. The Danube Delta is a vast wetland ecosystem that supports diverse aquatic life and serves as an important migratory corridor for birds. Effective wastewater treatment at Beli Manastir helps reduce nutrient and pollutant loads entering this sensitive downstream environment.
